なつている。 Inside the building, there is a tank room, a pump room, a maze of pump room entrances, and a passageway. Shielding walls have been installed in high-dose areas such as tanks and pump rooms, and low-dose areas such as passageways, as it is necessary to protect the radiation levels in the low-dose areas. Therefore, the shielding wall 6 of the tank 1 is connected to the passage 12 from the tank 1.
It is installed to shield radiation from radiation.
Furthermore, a labyrinth 8 is installed to shield radiation from the entrance/exit 2. Similarly, in the pump room where the pump 3 is placed, a shielding wall 7 for shielding radiation from the pump 3 to the passage 13 and a maze 9 for shielding radiation from the entrance/exit 4 are installed. Furthermore, a shielding floor 17 is installed for shielding radiation from the pump 3 to the passage 12 on the second floor. The shielding wall 5 between the tank 1 and the pump 3 is designed to prevent the waste liquid flowing out from the tank 1 from flowing into the passage through the chamber of the pump 1 in the event that the tank 1 is ruptured. The height of the tank 1 and the pump 3 are designed to reduce radiation exposure from the tank 1 to the pump 3. Therefore tank 1
Since the entrance/exit to the building cannot be installed at the same level as the floor, entrance/exit 2 on the second floor is installed for access.

１６を使用している。ポンプ３へのアクセスは、
通路１３から出入口４を通つて入る。 Access to the tank 1 is from the passage 12 through the entrance 2 and out onto the grating 18 . A ladder 15 is used to reach the bottom of the tank 1, and a ladder 16 is used to reach the top of the tank 1. To access pump 3,
Enter from passage 13 through doorway 4.

る。 Waste liquid that flows out due to breakage of the tank 1 or the like is discharged through a drainage pit 10. Further, waste liquid that flows out due to pipe breakage around the pump 3 is prevented from flowing out from the chamber of the pump 3 into the passage 13 by a drain 14, and the waste liquid is discharged through a drain pit 11.

にもさらに遮蔽用迷路構造が必要となつていた。 In the conventional example, since the pump and the tank are arranged at the same height, each floor requires an area for the tank room, the pump room, the labyrinth structure of the entrance and exit of the pump room, and the passage. In addition, in consideration of the possibility that the waste liquid in the tank will flow into the tank room in the event of a tank breakage accident, the entrance and exit of the tank room will be installed at a position lower than the tank water level in order to prevent the waste liquid from flowing outside the tank room and spreading contamination. Since it is necessary to design the pump room so that there is no entrance, it is not possible to provide an entrance from the pump room to the tank room, and the structure is such that the tank room can be accessed from the passage on the second floor. For this reason, a maze structure for shielding was also required at the entrance/exit of the tank chamber.

The constituent elements of the present invention are that, in a radiation facility in which a tank room in which a tank containing radioactive fluid is installed, a pump room in which a transfer pump for transferring the fluid in the tank is installed, and a low-dose area are arranged, the pump room is installed. A low-dose area is placed on a middle floor adjacent to the tank room through a radiation shielding wall, adjacent to the tank room through another radiation shielding wall, and under the floor of the pump room through a radiation shielding floor. The entrance between the pump room and the low-dose area passes straight through the radiation shielding floor in the vertical direction, and the entrance between the pump room and the tank room runs straight through the radiation shielding wall. The internal structure of a radiation facility is characterized by a structure that penetrates horizontally in a state where the low-dose area is protected by a radiation shielding wall and a radiation shielding floor, and each entrance and exit is a straight-line structure with no maze. Although they exist as openings, one of the entrances and exits is on a vertical plane and the other is on a horizontal plane, so radiation passing straight from the tank room to the low-dose area is suppressed, and radiation from the pump is prevented from passing through where the pump is placed. Since the entrance/exit between the pump room and the low-dose area opens vertically on the horizontal plane, which is the floor, passage through the opening is suppressed compared to when the entrance/exit opens on the vertical plane. If the entrance/exit has an opening area that covers the vertical projected area of the worker, it will be enough for the worker to pass through, so it is better to make the entrance/exit with an opening area large enough to cover the height and width of the worker in the vertical plane. Since the opening area is small, the direct passage of radiation from the pump room to the low-dose area can be further suppressed, and the low-dose state in the low-dose area can be maintained without the need for a labyrinth configuration at each entrance. By arranging each room and low-dose area adjacent to each other to reduce dead space, it is possible to reduce the overall volume of the building without adopting a labyrinth configuration for entrances and exits.
以下、本発明の一実施例を第４図、第５図およ

An embodiment of the present invention will be described below with reference to FIGS. 4, 5, and 6.

床２１により遮蔽する。 Regarding the arrangement of the tank room and the pump room, a passage 13 is placed next to the tank 1, and a pump 3 is placed on the middle floor above the passage 13. a wall 6 that shields radiation from the tank 1 to the passage 13 on the first floor and the passage 12 on the second floor;
It is shielded by a shielding wall 20. Radiation from the tank 1 is shielded from the pump 3 side by a shielding wall 5. Similarly, passages 13 and 2 on the first floor from pump 3
Radiation to the passageway 12 on the floor is shielded by a shielding floor 17 and a shielding floor 21.

入口２を小さくすれば解決する。 In order to prevent radiation directly coming from the piping around the pump 3 and other radiation from contributing to the passage 13 side, the pump 3 is arranged deep from the entrance/exit 4. The waste liquid that flows out due to a rupture of the tank 1, etc., can be drained through a drainage pit 10, which is installed in the same manner as before. If the amount of waste liquid flowing out of the tank 1 exceeds the shielding floor 21, this can be solved by raising the shielding floor 21 and making the entrance/exit 2 smaller.

Install 4. Further, the structure is such that the outflowing waste liquid flows into the drain pit 10 on the tank 1 side by providing a slope on the shielding floor 21 toward the entrance/exit 2 side. Furthermore, if airtightness is required between the pump 3 and the passage 13, this can be achieved simply by installing an airtight cover on the inlet/outlet 4. Access to the pump 3 is provided by means of a movable staircase 19 from the passageway 13 to the entrance/exit 4. The tank 1 is accessed through the same route as the pump 3 and exits from the grating 18 of the tank 1 through the entrance 2. When going to the bottom of the tank 1, use the ladder 15, and when going to the top of the tank 1, use the ladder 16.

路を設置する必要があつた。 According to this embodiment, the following advantages can be obtained when compared with the conventional arrangement structure. Previously, in order to prevent waste liquid from leaking out of the tank room in the event of tank damage, access to the tank room in the high-dose area was accessed from the passageway in the low-dose area on the second floor, as there was no entrance/exit on the first floor. Therefore, it was necessary to install a maze at the entrance and exit of the tank room in order to maintain the radiation level in the low-dose area.
本発明では、中階にポンプ室を設置しているた

ては、両室間に迷路を設置する必要はない。 In the present invention, since the pump room is installed on the middle floor, it is possible to access the tank room from the pump room. The pump room and the tank room are in the same high-dose area, and the shielding wall 5 is a separation wall for the purpose of reducing radiation exposure when working near the pump for pump inspections, etc. Therefore, the tank should not be directly visible from the vicinity of the pump. There is no need to install a maze between the two chambers.

口には迷路が不要となる。 Furthermore, regarding the entrance and exit of the pump room, in the conventional example, the pump room and the passage were arranged in a flat manner, so it was necessary to install a maze in order to maintain the radiation level in the passage, which is a low-dose area. However, in this example, the radiation level to be maintained only needs to be maintained within a range below human height from the floor, so the entrance and exit should be located at a location where pumps, piping, etc. that are the source of radiation cannot be seen directly from the human height range. In addition, the distance from the entrance to the human height position is ensured, and since the pump chamber entrance is accessed from above and below, the entrance 4 only needs to be wide enough for human access. The width of the entrance and exit can also be made smaller than before. Therefore, there is no need for a labyrinth at the entrance to the pump chamber.
以上の２つの迷路が不要となることと、ポンプ

減効果が得られる。 By eliminating the need for the two mazes mentioned above and by locating the pump room in a space that was previously a dead space above the passageway, the amount of materials required for the maze is reduced, and the volume of the entire building is reduced. Reduced. As an example, if we consider a radioactive waste liquid treatment equipment building, in the conventional case, there would be a tank room, a pump room,
The total floor area of the maze and passageways is approximately 900m2 . When the arrangement of this embodiment is applied to this system, the required floor space is limited to the tank room and the passageway, resulting in a total of 600 m 2 , resulting in an effect of reducing the building floor area by approximately 300 m 2 .

不要となる。 Furthermore, in the conventional example, the pump chamber is at the same height as the tank floor, so when the pipes in the pump chamber break, all of the waste liquid in the tank flows into the pump chamber. Therefore, in order to prevent the waste liquid from flowing into the passageway and contaminating the low-dose area with radioactivity, it is necessary to install a gate of sufficient height at the entrance and exit of the pump room, and the pump room also requires a large capacity for wastewater treatment. It was. In this example, even if a pipe breaks in the pump room, the pump room is arranged at a high level, so the waste liquid flowing out will stop at the same level as the break port, so it is possible to drain the waste liquid in the tank in advance. disappears. Furthermore, if a slope is provided on the floor of the pump room so that the waste liquid flows through the tank room inlet/outlet 2 to the tank room drain pit 10, waste water treatment in the pump room becomes unnecessary, and the waste liquid flows like the conventional pump room inlet/outlet. It is also not necessary to install a fence.

According to the present invention, by installing the transfer pump on the middle floor, in addition to making it possible to effectively utilize the conventional dead space above the passageway, the maze structure of the pump room entrance and exit and the labyrinth structure of the tank room entrance are no longer necessary. , the amount of shielding walls is reduced, and the required floor area of the building can be reduced, resulting in the effect that the building construction cost can be significantly reduced.
